Our Company was founded with the strategic vision to become a leading, high-growth provider of information-based advisory services. We continue to believe that our vision will be realized through the acquisition, integration and successful operation of market-leading brands within the data, analytics and advisory industry. Our private and public sector clients continue to face significant technological, business and economic challenges that we believe will fuel demand for the professional services we provide. We are focused on providing unique solutions that solve key client problems. In the private sector, for example, we believe that companies will continue to face significant challenges associated with globalization and technological innovation, including the need to decrease operating costs, increase efficiencies, compete against new market entrants and evaluate and adopt increasing numbers of emerging and transformational technologies, such as artificial intelligence. Similarly, public sector organizations at the national, regional and local levels increasingly must deal with the complex and converging issues of outdated technology systems, reduced budgets and an aging workforce. Overall, we believe the global marketplace dynamics at work in both the private and public sectors support growing demand for the professional services, analytics, platforms and advice ISG can provide. In this dynamic environment, the strength of our client relationships greatly depends on the quality of our advice and insight, our unique and valuable datasets, the independence of our thought leadership and the effectiveness of our people in assisting our clients to implement strategies that successfully address their most pressing operational challenges. We are organized as a corporation under the laws of the State of Delaware.
